Principles of Adaptive Filters and Self-Learning
Systems (2005) – Solutions Manual – Zaknich
What is a well-established technique in digital imaging? - answers-Digital image filtering
Which software is known for digital image filtering? - answers-Photoshop
What type of devices commonly use image filtering? - answers-Decent smartphones
What systems are capable of image filtering? - answers-Robust PACS
Which types of images frequently undergo image filtering? - answers-CT and MR images
In which medical imaging technique has image filtering been applied for several years? -
answers-Ultrasound
How has image filtering in ultrasound changed over the years? - answers-It has become more
sophisticated with dramatic image changes.
What is real-time adaptive filtering primarily used for? - answers-To reduce speckle artifact,
often referred to as speckle reduction techniques.
What is a secondary goal of real-time adaptive filtering? - answers-To enhance borders.
What type of function is real-time adaptive filtering? - answers-A purely post-processing
1
, function.
What does real-time adaptive filtering involve? - answers-Computational analysis.
What is the purpose of smoothing filters in imaging? - answers-Reduce noise (speckle), increase
contrast resolution, and improve imaging of scatter reflectors.
What is the purpose of edge enhancement filters in imaging? - answers-Highlight borders and
boundaries, and enhance specular reflectors.
What is the purpose of real-time adaptive filtering? - answers-To enhance tissue borders and
reduce acoustic noise simultaneously.
What is a key feature of real-time adaptive filtering? - answers-It is capable of extremely fast
digital processing for real-time image filtering.
How does adaptive filtering analyze images? - answers-It analyzes and alters each stored image
while comparing it to other acquired frames over time.
What types of comparisons does adaptive filtering perform? - answers-It compares images
locally (within a frame) and temporarily (frame to frame).
What is the intended use of real-time adaptive filtering? - answers-It is intended to be used as
an adjunct with spatial compounding.
What effect does acoustic noise have on detection of low contrast reflectors? - answers-Speckle
reduces detection of low contrast reflectors and decreases the signal-to-noise ratio (SNR), thus
affecting contrast resolution.
